Pop stars and former Celebrity Big Brother housemates Jedward risked serious injury last night when a ticketholder at one of their gigs started pelting them with bottles.

The Irish twins - John and Edward Grimes - were midway through their performance when a fan launched water bottles through the air from the crowd in an attempt to hit them.

They were playing the Engine Room in Lincoln as part of the university's Quack night when the incident took place, and narrowly avoided getting struck by the flying projectiles.

The Lincolnshire Echo reported that the culprit was eventually escorted out of the concert for their actions.

Video footage of the performers, decked out in leather jackets, reacting to the incident has emerged online.

Students took to social media insisting it was just one ‘bad apple’ who spoiled an otherwise enjoyable night.

A University of Lincoln student, who appeared to take responsibility for the incident on social media tweeted: “Kicked out for throwing three bottles at Jedward. Worth it.”

The tweet has since been deleted but a Jedward fans have made a point of responding to the student online and demanding he show more respect to the musicians.

James Brooks, chief executive officer at the Student’s Union, said: “The Engine Shed is appalled by the behaviour that took place at last night's Quack and apologises unreservedly to Jedward for the unacceptable treatment that they experienced."

'The students involved in throwing plastic bottles have been identified, and the situation was dealt with swiftly and professionally by the Engine Shed staff, we are now investigating the incident with other agencies as a matter of urgency.

“The bottles were plastic and although no injuries were sustained to either John or Edward, the behaviour is unacceptable, and will be dealt with accordingly by the Students’ Union and the University.”

Unfortunately, it's the second time in recent memory that acts performing at the venue have been targeted while on stage.
